How do I change the Copyright information on a rendered file before rendering?
Looking at the Blender source code, the copyright seems to be hard-coded with the line:


  [qtexport->movie setAttribute:@"Made with Blender" 


For this reason I don't think the copyright message is configurable via the interface nor via Blender's Python API, meaning the only option is to edit the copyright manually after rendering or see if you can write a Python script to do this (which would be a question for StackOverflow) and get it to execute automatically after rendering with an app.handler.
